What Are the Symptoms of Poor Car Battery Contact?
2 Answers
Automobile battery poor contact symptoms: unstable idling, battery damage, and damage to the generator. The following are the maintenance methods for automobile batteries: 1. Regularly check the electrolyte: The electrolyte level should always be kept between max and min. Check it once a month and supplement with distilled water (pure water) as needed, but never add acid. 2. Maintain normal voltage: When the battery voltage is insufficient and the lights are dim or the engine struggles to start, perform an external charge promptly. 3. Charge in time: Prevent the battery from being overcharged or chronically undercharged. Overcharging can cause active material to fall off, while undercharging can lead to plate sulfation. Ensure the regulator voltage is neither too high nor too low. 4. Regularly check the vent holes: During use, frequently check if the vent holes are clear to prevent battery deformation or explosion.
I noticed that when the car battery has poor contact, starting the vehicle becomes particularly difficult. It takes forever to turn the key and ignite, sometimes with no response at all, which is really frustrating. The lights also flicker, especially at night when the headlights are unstable, and the radio cuts in and out, with music suddenly stopping and then resuming. Upon inspection, I found white corrosion on the battery terminals and a faint burnt smell. That time, the car broke down on the highway, and I had to call a tow truck, costing quite a bit for repairs. Later, I learned to clean the terminals every few weeks, using a bit of baking soda solution to remove the corrosion and applying petroleum jelly for protection, which basically prevents such issues. If I had paid attention to these things earlier, I wouldn’t have had to deal with all that hassle.
